\ and also means for causing the gripper jaws than the corner jaws, so aste insure that the portion-of Vthe upper at the end of the toe, which it is desired to pull with the greater strain, will be held securely without any tendency to slip in the gripper jaws.

The above and other 'features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawings and pointed out in the claims.

Since the general organization of the machine in which the invention is herein shown as embodied is fully illustrated and described in the copending application of which this application is a division, and in the` prior Letters Patent referred to in the copending application, only such portions of line in relation to tie lines of the last.

the machine as are intimately related to the features ot the present invention will be described herein in detail.

For pullingthe upper over the last themachine is provided with side grippers, comprising at each side of the forcpart two pairs of gripper jaws 2, as common heretofore, and .with a toe gripper the construction of which for purposes of the present invention will be hereinafter more particularly set forth. `The opposite side grippers are connected respectively to different updraw levers 4, one of which is shown in Fig. 1, the rear ends ot' these levers being' swivelled in blocks 6 which are slidably mounted on updraw rods 8 fast on a vertically movable operating slide 10. Encircling the rods 8 and bearing downwardly upon the blocks" G f through tension adjusting wedges 12 are updraw springs 14 through which movement is i..

operated by a cam 26 on the shaft 1S. Movement is imparted to the shaft 18 intermit-V tently in the course of the cycle of operations from a power shaft (not herein shown), under control of mechanism of the character illustrated in Letters Patent No.

791,986 granted on June 6, 1905` upon an,

application of R. F. McFeely, this mechanism including` a treadle-operated red 28 which is moved upwardly to start the machine at each stage of the cycle. The work Fig. 1, with the bottom of the insole in engagement with a sole rest 30, Vand it will be understood that in the first stage of the cycle the grippers are Operated through the mechanism above described to grip and to pull the upper, the sole rest 30 having imparted to it a short downward tipping movement by the action of a cam 32, and at the end of this stage of the cycleV the machine comes automatically toa stop with the upper held under tension for the inspection of the operator and for such supplemental operations as may be necessary or desirable. for example to vary the force of the )ull of one or vmore of the grip ers or to adjust the tlip n this first stage of the cycle also a heel rest 34 is moved forwardly into supporting engagement with the rear end of the shoe, this heel rest being preferably constructed as Vshown in my copending application above mentioned.

For purposes of this invention, the tee gripper is constructed `as shown in Figs. 9 to 11, inclusive. Similarly to grippers heretofore in use in machines of the general type 'ill `is presented to the machine is illustrated in.

The pro` vvision of means for applying thus a positively determined greater degree of gripping pressure to the upper at the end of the toe than toportions of the upper engaged at lation of ja lever (not shown), as `inprior` machines. VThe conditions observed at this stage sometimes also render it desirable to move one or more of the grippersin a direction toinerease or to lessen the forceof the pull. For example, it may be `desired to apply a harder pull through the side grippers to draw the upper closely to the c `last at the back of the toe, or by relaxing the force of the pull at one side and increasing it at the `other side to adjust the upper by slipping it transversely of the'last. At the toe,ymoreover, itmay be desired to increase or to lessenthe force of the pull, for example in order to straighten the tip line, or conditions may render it necessary to adjust the toe gripper on the upper, for example to position the gripper jaws at a higher elevation in preparation for subsequent operations. For these and other purposes, the machine is provided with power means for im arting supplement-al movements to the difiiarent grippers selectively, as shown particulary in Fig. 2 of the drawings and more in detail in other figures comprising Figs. 3 to 8, inclusive. It will be noted that the right-hand side gripper lever 4` is connected at its rear end (Fig. 2) by a link 112 to an arm 114 which is vfast on a rock shaft 116 mounted to turn in bearings in a bracket 118 on the rear of the machine,` the shaft 116 having fast thereon on arm 120` connected by a link 122 to a block 124 fast on the upper end-of a rod 126which is mounted to slide `vertically in a support 128inounted on the righthand side ofthe machine Fast on the lower end of therod 126 (Fig. 4) is a block 13() on which is pivoted. at 132 a double or forked rack member 134 having opposite sets of rack teeth 136 and 138 arranged for engagement alternatively with the teeth of a pinion 140 fast oiiafshaft 142. Movement `in the direction of `thearrow may .beim` parted toithis shaftby any convenient or suitable means, such as an electric motor (not shown) connected by a belt 146 (Figi, 2) to a pulley 148 which is fast on a sha. 150 mounted `to turn in bearingaformed in a bracket mounted on the side of` thermacliine. The shaft 15() carries an eccentric 152 which operates a pitman 154A connected to a lever 156 mounted to oscillate on a fixed pivot 158, the 1ever1156 being connected by a link. 160 to an arm 162 whichl is fast on a sleeve 164 (Fi 8) `serving as one of the members of a lorton clutch mounted on the shaft 142. Inside of thesleeve 164 lis a cooperating clu-tch member` 166 with a series of rolls 168 which act in aV wellknown man# ner totransmit movements of the sleeve 164 in the direction of the arrow `to the shaft 142. It will be understood that the arm V162 is rapidly oscillated at 'all times through its connections to the metonand that as a result intermittent turning movements all in the same direction are imparted tov thepinionv140, reverse movement of the shaft 142 and its pinion bein `prevented by the action` of a second` Orton clutch 170 `mounted adjacent tothe driving clutch, as

shown in Fig. 5,.)and providedwith an arm 172 (Fig. 8)` which isfast to` the frame. While ithas been found convenient in the organizationherein shown thus to impart intermittent turning movements tothe pinion 140, it is to be understood that the invention is not dependent upon or restricted to movement of that particular character.

0 By reference to Fig. 4 it will be seen that if the front seriesof teeth136 on the member 164 are moved-'into engagement with the pinion 140, the pinion will act on these teeth through the connections above dej Y scribed to impart downward movement' to the rear end of the right-hand gripper lever 4 to move the gripper in the direction to in crease the foi'ceof its pull on the upper, and that if tlie rear series of teeth 138 are engaged with the pinion the opposite result will be effected and niovement'iniparted to the gripper in the,` direction to relax the `force of the pull. For accomplishing either of these results at will the rack member 134 is under control of a handle 174 (Fig. 2) through connections includinga rocker 176 mounted to turn about the axis of the shaft 142 and having projections 178 which bear respectively on the shaft and on a bushing encircling the pinion 140 (Fig. 5), and

which embrace and `guide between them the lower end of the rack member 134': An upward and rearward extension oiff theroclier V17 6 is provided with a roll 180" positioned in a vertical slot 18,2 in the rackmeniber 134, and a forward extension of the rockeris engaged on its upper and lower faces by spring Y member :ind to die rod and Y plimgers 184 .whereby -the rocker is mail? tained normally in a @entraner nentrel .poen tion with both .series.o'f-lzroli teeth 1326 Lnd 138 out of engagement with the lpinion 140. handjleill is connected to the rocker 1756 .by nieensroi n block 186 which ejpivoted et 188 Aon .the forward extension of the rocker Torurderstand the notion (of tire iangdle 17,4 on the rocker lGf-it is n'ecesga-ry to reifer at thispoint to means :provided for locking tlle rod 126 against return upward movement from any poeigtion to Vwhich iti is moved: in
